[texts]Abductive Reasoning by Children - Heidi Kloos, Guy Van Orden
Children can link facts and events into integrated beliefs. This ability of the mind to combine facts to form higher-order Gestalts is central to many cognitive activities, including problem solving, analogical reasoning, and creative thought. In fact, it is central to the abduction of meaning: the creation of a self-sustaining pattern of ordered facts that are combined in the larger Gestalt. Abduction has mostly escaped experimental investigation, possibly because it often emerges instantly and...

[texts]scaling relation for a compact crumpled thin sheet - Bai,Wubin /Lin,Yen-Chih /Hou,Tzon-Kun /Hong,Tzay-Ming /
A high-pressure chamber was designed to study the crumpling of thin sheets beyond the power-law regime. Preceded by a smooth transition, the crumpled ball that characterizes the high-pressure state contains less than 50% air and exhibits separate ordered domains. All the data for different sheet thickness, size, and even number collapse to a master line when using volume ratio and pressure as the plotting parameters...

[texts]Stability, Oscillatory Modes, Bifurcations, and Chaotic Behavior of Complex Systems with Phase Control
This paper deals with the problem of nonlinear dynamics of complex system with phase control combining phase-locked loop and automatic gain control loop. The behavior of the examined system is described by nonlinear two- and four-dimensional sets of differential equations with periodical nonlinearities. Stability of synchronous mode, bifurcations determining boundaries of domain with quality different behavior of the considered system, and oscillatory modes arising in domain where synchronous mo...

[texts]Measurements of Nonlinear Refractive Index of Optical Fiber by Using Multiple Interference in OFRR - Yoh Imai, Hirohisa Yokota, Satoshi Yamauchi
In this paper, a new method for measuring the nonlinear refractive index by using the multiple interference phenomenon occurred in an optical fiber ring resonator (OFRR) is proposed. In OFRRs, input light and circulated light components are added in succession, and then, result in forming a multiple interference output. The OFRR output exhibits nonlinear characteristics between the input and the output power due to the optical Kerr effect, as the input light power increases, as is shown in the b...

[texts]Embodiment of Consciousness - Bernhard Bierschenk
The present article is based on the premise that mind is an emergent property of the processes that produce consciousness. Any scientific understanding must necessarily consider the need of an explanation of consciousness. Instead, the non-sense property of traditional scientific modelling appears to hide the phenomenon. In contrast, the explored hypothesis is based on the assumption that the meaningfulness of natural language is the carrier of consciousness...

[movies]MIT 6.832 Underactuated Robotics, Spring 2009 - MIT OpenCourseWare
Instructor: Russell Tedrake Robots today move far too conservatively, using control systems that attempt to maintain full control authority at all times. Humans and animals move much more aggressively by routinely executing motions which involve a loss of instantaneous control authority. Controlling nonlinear systems without complete control authority requires methods that can reason about and exploit the natural dynamics of our machines...
